Final answer:
The total area of the basil plot is 25/64 square yards and the perimeter of the fence is 20 feet.
Step-by-step explanation:
To find the total area of the basil plot, we need to multiply the length of one side by itself. So, 5/8 yard x 5/8 yard = 25/64 square yards. To find the perimeter of the fence, we add up the lengths of all four sides. The length of one side is 5/8 yard + 2 feet (converted to yards) + 2 feet (converted to yards). So, one side is 5/8 + (2/3) + (2/3) yards. Multiply this by 4 to get the perimeter of the fence in feet.
